IMPROVEMENT IN BOILER-FEEDERS.

Specification forming part of Letters Patent No. 155,004, datedSeptember 15, 1874 application filed July 18, 1874.

To all whom it may concern:

Be it known that I, PHILIP T. BROWNELL,

of Elmira, in' the county of Ohemung and State of New York, haveinvented a new and Improved Boiler-Feeder, of which thefollowing is aspecification:

. My invention consists of a double-chambered hollow cylinder or drum,having a slow oscillatory movement imparted to it by'any suitableconnection with the operating-gear of the engine, whereby ports in thechambers are alternately caused to register with ports in the heater anda feed-pipe to the boiler, also with a steam-pipe connectingwith theboiler at the water-level, in such manner that one of G, near the top,and another,'H, near the bottom of each compartment, with a valve-faceat both sets of ports, working steam-tight, the one against the mouth ofpipe J, by which the feed-water enters the boiler, and the other againstthe ends of the branched steam-pipe K, openings L into the heater M, andthe openings N into the feed-water pipe.

The drum is oscillated forward and backward by the lever 0 and crankedwheel P, which are supposed to be operated by the engine or anycompetent means.

As represented in Fig. 1, the compartment B is represented as receivingwater from the pipe N in the heater, while compartment 0 is receivingsteam from pipe K, and discharging its water into the boiler by pipe J.When the of reference indicate correcylinder is next shifted by thelever O, the

ports of compartment B will register with pipes J and K, so that thewater will flow from it into the boiler, while the ports G ofcompartment (3 will register with pipe N to receive the water, and itsports H will be cut off from pipe J. When the ports G pass the openingsL into the heater they allow the water of condensation in the heater toflow into the compartments 0 or D, so that it finds its way into theboiler.

The drum A is inclosed in an outer shell, Q, in which it will besurrounded by steam or hot water admitted to it from the steam-pipe, oneof the branches of which is uncovered when the other is registering withthe drum, 7 the object being to utilize the steam-pressure for forcingit against the valve-seat, so as to prevent leakage from one port toanother. The steam-pipe K connects with the boiler at the water-line, sothat, in case the water rises up to and closes the mouth, the feed willstop until the water falls low enough to admit steam to the drum again.

The contrivance is also adapted to work as a steam-trap for steamheating apparatus, and

I propose to use it as such.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- 1. The combination of the compartments B G and portsG H of the oscillating drum A with the water-supply pipe N, the branchedsteam-pipe K, and the feed-pipe J, as and for the purpose specified.

2. The combination of the ports G of the compartments Band C of theoscillating drum A with ports L of the heater M and the water pipe N,for the purpose of taking off the wa* ter of condensation in saidheater, substam tially as'described.
